ADJUSTABLE CONNECTING-BAR FOB SWITCH-POINTS.

Specification of Letters Patent.

Application filed October 2, 1907. Serial No. 395,615.

To all whom it may concern:

Be it known that I, WILLIAM M. HENDER- SON, citizen of the United States, and resident of Steelton, Dauphin county, State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Connecting-Bars for Switch-Points, of which the following is a full, clear, and exact descrip tion, reference being had to the accompanying drawings, of which Figure 1 is a plan view showing my invention as applied to a split switch rod having a switch stand connected thereto. Fig. 2 is an end elevation, and Fig. 3, a plan view of my double adjusting nut, showing one form of connection between the same and the switch stand rod. Fig. 4 is a similar elevation, and Fig. 5 a similar plan view to Figs. 2 and3, showing a modified means of securing the switch stand rod to said double nut. Fig. 6 is a section on the line 6-6, Fig. 1, showing the detachable connections between the switch-rod and the lugs on-the point rails.

The object of this invention is to provide a ready means for adjusting the relation of either point of a split switch to its correspond ing stock rail, independent of any adjustment of the other rail; also to provide a ready means of adjusting the connection between the switch rod and the switch stand, without affecting the gage or position of the point-rails; whereby in placing the switch stand in position it is unnecessary to put it in its exact relation to the switch, but the connection of its operating rod to the switch rod may be shifted longitudinally of said rod as desired.

In the drawings :-1, 1 indicate the usual point rails, and 2, 2, the stock rails of a split switch. Connecting the point rails adjacent the point thereof is the usual switch rod, 3, in this instance divided into two portions, whose adjacent ends are screw-threaded, as seen in the drawings; each of said threaded portions being provided with a thread running in the same direction; that is, in this instance, both are provided with right-hand threads. Secured to these ends is a double nut, 4, having means, such as the lug, 5,'to which it may be connected with the switchstand, 7, by the usual rod, 8; although the character of the connection between said double nut, 1, and the switch rod is immaterial. For instance, instead of that just described, and illustrated in Figs. 1, 2, and 3, a lug such as 9, in Figs. 4 and 5, may be used,

having a longitudinal hole therethrough, through which extends and is adjustably secured by nuts 10 and 11, the screw-threaded free end of the switch stand rod, 8, as seen in Figs. 4 and 5. The switch-rod, 3, is con nected in well known manner to the pointrails, 1, 1 of the switch, in this instance by the usual box-lugs, 12, through the downwardly extending portions of which the ends of said rod pass, and are pivoted upon the bolts, 13.

In applying to a switch, the ends of the bars, 3, are screwed into the double nut, 4, to bring the bolt holes thereof a distance apart equal to the bolts through the lugs 12, on the opposite switch points. The bars are then inserted in the lugs, 12, and the bolts put in place, securing the lugs, 12, and the bars, 3, together in well known manner. The switchstand, 7, is then put in place opposite the switch point and secured to the ties, its distance from the lug, 5, being ap proximately that of the length of the bar, 8. The double nut, 4, is then rotated upon the bars, 3, along which it longitudinally adjusts itself, by reason of the right-hand threads on said bars, until the lug, 5, comes into proper relation with the end of the switch connecting rod, 8, which is then secured thereto.

It will be observed that when it is desired to adjust the throw of the switch in either direction that is, toward or away from the switch stand; all that is necessary to do is to detach the end of the rod, 8, from the lug, 5, screw the double nut in either direction, as the case may be, and reconnect the rod, 8, with the lug, 5, the gage of the switch point rails remaining the same. Should, however, it be desired to change the gage of the point rails without affecting the throw of the switch, either one of the bars, 3, may be disengaged from its lug, 12, screwed longitudinally in the double nut, 1, and then resecured in place to the lug, 12.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a railroad switch, the combination with the point-rails, of the connecting bars respectively detachably secured thereto, whose adjacent ends are each provided with screw threads of the same direction, together with the double nut screwed on to said adjacent ends, substantially as set forth.

2. In a railroad switch, the combination 7 whose adjacent ends are each provided with with the point-rails, of the connecting bars screw threads of the same direction, the respectively secured thereto, whose adjacent double nut screwed on to said adjacent ends, ends are each provided with screw threads of I together with the switch stand adjacent the the same direction, the double nut screwed switch point and having the connecting rod on to said adjacent ends, together with i Whose inner end is connected to said double the switch stand adjacent the switch point I nut, substantially as setforth. and having the connecting rod whose inner end isconnected to said double nut, subj a'HiXed my signature. stenllany as l WILLIAM M.
